本文在非阿贝尔规范理论的有限维模型中,为微扰渐近展开的规范固定无关性提供了代数证明。我们利用BRST形式体系和微扰理论发展了一个代数框架。我们的主要定理表明,在适当的横截性条件下,当规范固定条件在保持这些假设的光滑形变下变化时,可观测量的归一化期望值保持不变。
英文摘要
This paper provides an algebraic proof of the gauge-fixing independence of perturbative asymptotic expansions in a finite-dimensional model of non-Abelian gauge theory. We develop an algebraic framework using the BRST formalism and perturbation theory. Our main theorem shows that under appropriate transversality conditions, normalized expectation values of observables remain unchanged under smooth deformations of the gauge-fixing conditions that preserve these assumptions.
